T MILLIE PATENT HOLDING CO. INC.,

OF NEW YORK, N. Y., A CORPORATION OF TEA. CARTRIDGE.

Application filed February '1, 1923. Serial No. 616,317.

T 0 all whom it may concern:

Be it known that I, BENJAMIN Hmsorr- HORN, a citizen. of the UnitedStates, and resident of the city of New York, in the county of Bronx andState of New York,

have invented certain new and useful Im provements in Tea Cartridges, ofwhich the following is a specification.

The present invention relates to improvements in tea cartridges forpercolating or extracting the flavor from tea-leaves or coffee. Theinvention pertains'more particularly to that type of cartridges. whichis described in U. S. Letters Patent No. 1,310,796, granted to me onJuly 22, 1919.

In this patent a cartridge is described, comprising a bag of textilefabric, having its mouth drawn into folds, the mouth of the bag beingclosed by a metal strip, in the form of a ring, which engages andcompresses the folds, in combination with a suspending string which isattached to said bag by said strip. In making these cartridges,obviously, first a bag must be formed on a sewing machine from a pieceof textile fabric.

The main. object of the present invention is to form a tea cartridgefrom a piece of textile fabric without first producing a bag, therebygreatly reducing the cost of manufacture.

With these and other objects in view, which willmore fully appear as thenature of the invention is better understood, the same consists in thecombination, arrangement and construction of parts hereinafterdescribed, pointed out in the appended claim and illustrated in theaccompanying drawings. it being understood that many changes may be madein the size and proportion of the several parts and details ofconstruction within the scope of the appended claim,

without departing from the spirit or sacrificing any of the advantagesof the invention.

One of the many possible embodiments of the invention is illustrated inthe accompanying drawings, in which Figure l is a plan view of a pieceof fabric. front which the container of the cartridge formed; Fig. 2 isa perspective View i the container before its mouth is closed;

and Fig. 3 is an elevation of a completed tea cartridge, constructed inaccordance with the present invention.

In producing the cartridge, first a iece 10 of open-mesh textilefabric,preferably of square or quadrangular configuration, is cut from a strip,tea-leaves or coffee, sufficient for a single brewing, being placedcentrally thereon, and the edges of the said fabric piece gatheredtogether, as shown in Fig. 2 of the drawings, whereby a bag-likereceptacle 11 is obtained, within which the tealeaves or coffee areconfined. The mouth of the receptacle so formed is then closed, byapplying thereto a metallic strip 12, that is shaped to assume the formof a ring, which embraces the folded portion of the receptacle below itsmouth, holding the folds under compression, so as to prevent escaping ofthe contents. The strip must, obviously, be made of non-corroding metalor of a metal that is properly prepared to prevent corrosion. For thepurpose of facilitating the handling of the cartridge, there is fixedthereto a flexible means, such as a string. 13, to which is attachedatits free end a handle 14, for instance of cardboard. This string servesalso as the means for suspending the cartridge from the receptacle,

such as a tea-pot or coffee-pot, in which the extraction is to takeplace. The string is secured to the cartridge by placing it against thefolded mouth portion of the receptacle 11 before the strip 12 is formed.

From the foregoing it appears that the receptacle 11 is seamless, andthat the ringshaped closure strip 12 constitutes the means which holdsthe gathered edge portions of the fabric piece under compression, toform a receptacle therefrom.

In brewing tea or coffee with the improved device, the cartridge istaken hold of by its handle 14 and lowered into a pot, the free end ofthe string and handle being permitted to hang over the mouth of the ot,after which its cover is put in place. he cover thus holds the outer endof the string and handle ready for further operation. Into the pot ispoured a suitable quantity of boiling water, either before or after theinsertion of the cartridge. When sufficient essence has been extractedfrom the'tealeaves or coffee within the cartridge, the pot cover isremoved and the bag withdrawn by grasping its handle 14.

What I claim is :-1-

A device for extracting essence from tealeaves or coffee, comprising apiece of textile fabric having its edges gathered to gether so as toform a seamless receptacle,

and a metal strip engaging and compressing the mouth portion of thereceptacle so formed so as to close the same.

Signed at New York, in the county of New York and State of New York this23rd day of February, A. D. 1922.

BENJAMIN HIRSCHHORN.
